Removed the CDV yesterday. I definitely notice a difference, IT DRIVES NORMALLY NOW.
Seriously though, it's like the difference between when you tell someone else how to make your coffee for you and when you make it for yourself. Without the CDV it's the way it should be and always has been in other cars. |

BMW is still independent, not owned by anyone else, and they remain very profitable. No bailouts needed for them. You dont get that way, and stay that way, by making dumb financial choices. |

It feels great, I love the change. With the SSK + pulling left on 1->2 shifting is such a pleasure now.
I always knew it would feel better without the cdv; my concern was wear and tear on the car since BMW claims they added it to reduce drivetrain shock. After thinking about it, so many people have removed it from both this car and the e46m, and after this many years (6+ for this car, 12+ for the m3) I still haven't come across a thread with drivetrain damage. I wonder if BMW added it as an anti-hooning measure, rather than a real longevity concern.

It's probably like the electric steering of the non-M. When I had my first Z4 I didn't mind the electric steering at all. But after owning the M for a while, I realized how much, in retrospect, I hated the electric steering. When you don't know better the little annoyances are easily dismissed. Once you know better, they're insurmountable first world problems Your clutch is still much shorter/harder than mine, I wonder if it's a coupe/roadster difference (since you guys also got the shorter steering lock + stiffer suspension), or just a car/car difference. Your car also sold me on an exhaust. I don't think I can go quite as loud as you, but it sounds amazing!

Late to the party but $.02
There is no mastering of the clutch with a CDV installed.
The removal is a no brainer mod. Especially to lifelong experienced MT drivers Of course, as always, IMHO

Did anyone have problems bleeding their clutch after the CDV delete? This weekend I installed a Rogue SS clutch line (and removed the CDV), plus I installed Stoptech SS brake lines.
I had just enough fluid to bleed everything. My brake pedal felt good with the car still on jackstands, but the clutch pedal drops straight to the floor. Now I'm waiting for more ATE super blue fluid to arrive while I wonder if I just need to bleed the clutch again, or if I've got bigger problems. I hope I don't have to remove the slave cylinder and buy one of those slave cylinder bleeding tools. It looked like removing the slave would be a tight fit. |

I did the CDV delete a few years ago and it it changed things to where I thought it should be.
I then bought the UUC clutch stop kit recently and it was again a nice adjustment in user friendly tweaks. |

This is the most recent thread I found on the topic.
My Indy shop replaced the stock slave cylinder line with a SS line last week and in the process the CDV was removed. It's in a plastic bag on my workbench where it belongs IMESHO. Good riddance! I can shift smoothly again. |

I just acquired my Z4M this summer. My first impression was that the clutch release was kind of Numb. This is my first BMW so I figured it was as design for "comfort", Which seemed odd for an ///M. A greater concern was when I was putting my foot into the accelerator when going into 2nd gear, it always feels like the clutch is slipping. Well, Come to learn of the CDV, I guess it is slipping. I can't wait to get under the car and pull it out!

I've been driving my 06 Z4M for two weeks now. The clutch makes me feel like I nearly never quite get it right, but then I do a smooth quick shift and I think it's me, I need to just keep getting used to this. Now I'm convinced it's gotta go.....Question, where do I get the "regular " valve ? Parts store could not find it on their computer today. Or is it " better " to just take it out, connect line straight in ?
